We only process a demuxed sample at a time. Waiting until one is decoded to do the next pending ones.

We unfortunately can't store this information in the VideoInfo as typically the framerate isn't found in the container's metadata. Additionally, the VideoInfo object is readable-only as it is shared across threads.
As such, we can only estimate it as we demux samples.

Don't unnecessarily, create a decoder, flush, shutdown and create a new one on the first sample.

GPUProcessCrashTelemetryLogger is used to report telemetry of the time used to recover a decoder from GPU crash.
It uses MediaDecoderOwnerID to identify which video we're dealing with.
It uses MediaDataDecoderID to make sure that the old MediaDataDecoder has been deleted and we're already recovered.
It reports two recovery times, one is calculated from GPU crashed (that is, the time when VideoDecoderChild::ActorDestory() is called) and the other is calculated from the MFR is notified with NS_ERROR_DOM_MEDIA_NEED_NEW_DECODER error.

When GPU process crashes, the MediaDecoder, MDSM, and MFR are all destroyed.
So, we use MediaDecoderOwner to identify which video we're dealing with.

The nsRect.h and nsSize.h headers typedef nsIntRect to gfx::IntRect etc, so the
rect/size objects we use will be the same, just under a different name.
However the old headers #include a bunch of things we don't use, so we if we
use the gfx objects directly we end up with a smaller include graph.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

Note we put OnWaitingForKey() in MediaDecoderReader for MediaDecoder references
MDR instead of MFR. The function will be moved into MFR when we remove MDR and
have MediaDecoder reference MFR instead.

So we can reduce dependency on AbstractMediaDecoder.
See bug 1378295 comment 1 for the detail.
Note it is not ideal to repeat |init.mCrashHelper = ...| several times in
this patch. We will re-visit it to reduce code duplication after bug 1378295
is done.

This patch is going to loose the criteria of skip-to-next-key-frame.
The original rules are here:
http://searchfox.org/mozilla-central/rev/31311070d9860b24fe4a7a36976c14b328c16208/dom/media/MediaFormatReader.cpp#1559
Skip-to-next-key-frame is triggered if the playback position is LARGER than the next key frame time.
But, from the video-track point of view, when the skip-to-next-key-frame is triggered, it skips to the next-next key frame.
Here is an example, say, we are playing a media file with its playback position at time _a_,
and its video decoding is falling behind at time _v_.
The next key frame is at time _k1_ and next-next key frame is at time _k2_.
a
----|---------|---------|-------------|----------------> time
v k1 k2
When the playback position _a_ passes _k1_ (_a_ > _k1_), the skip-to-next-key-frame is triggered,
and the demuxer jumps to _k2_ directly.
The idea here is to give a chance when (_a_ == _k1_), let demuxer jump to _k1_ and see if the video decoding could catch up.
